How To Approach Psychogenic Symptoms

Remember back in 1997, the Pokemon seizure episode? Hundreds of children reported symptoms, including seizures, after watching a specific episode of the Pokemon cartoon that includes a sequence of flashing alternating red and blue lights.

What Is Type 3 Diabetes?

I’m always wary of new medical terms that seem to be used and promoted prematurely, when still in the hypothesis phase.

Sweetened Drinks and Risk of A-Fib

Yet again the public is being subjected to warnings about the potential health risks of consuming a common food item based upon insufficient evidence. Last month it was oat products, and now it’s sweetened drinks. The study is a prospective cohort study, which means it is observational. The researchers looked at over 200 thousand participants in the UK biobank. At the start...

Parasite Cleanse

Tik Tok is a cesspool of wellness pseudoscience and misinformation. All of social media has the potential to spread misinformation without any filter, but for some reason Tik Tok has become the preferred platform for the most outrageous claims and nonsense. A recent trend on Tik Tok (and within the wellness community generally) is the parasite cleanse. The idea is that many...
